You have completely untouched "Poles" among the Upper Siliesians imo.
I was somewhat in an argument with a German nationalist from there (myself being a German nationalist), that completely rejected the applicability of genetic results showing that he and his family had kind of 93% EE at 23andMe (and 2% French & German). Which is above the Polish mean for EE even? However, I know exactly how these folks voted and identified still in 1907. :)
